Horse behavior is best understood from the view that horses are prey animals with a well-developed fight-or-flight response. Their first reaction to a threat is often to flee, although sometimes they stand their ground and defend themselves or their offspring in cases where flight is untenable, such as when a foal would be threatened. [1 ...
t. e. A frog in frogspawn. In biology, offspring are the young creation of living organisms, produced either by a single organism or, in the case of sexual reproduction, two organisms. Collective offspring may be known as a brood or progeny in a more general way. This can refer to a set of simultaneous offspring, such as the chicks hatched from ...
Reproduction (or procreation or breeding) is the biological process by which new individual organisms – "offspring" – are produced from their "parent" or parents. There are two forms of reproduction: asexual and sexual . In asexual reproduction, an organism can reproduce without the involvement of another organism.
An anesthetic machine with integrated systems for monitoring of several vital parameters, including blood pressure and heart rate. Purpose. assess the general physical health of a person. Vital signs (also known as vitals) are a group of the four to six most crucial medical signs that indicate the status of the body's vital (life-sustaining ...
Fertility. Fertility in colloquial terms refers the ability to have offspring. In demographic contexts, fertility refers to the actual production of offspring, rather than the physical capability to reproduce, which is termed fecundity. [1] [2] The fertility rate is the average number of children born during an individual's lifetime.
Lethal white syndrome ( LWS ), also called overo lethal white syndrome ( OLWS ), lethal white overo ( LWO ), and overo lethal white foal syndrome ( OLWFS ), is an autosomal genetic disorder most prevalent in the American Paint Horse. Affected foals are born after the full 11-month gestation and externally appear normal, though they have all ...
Birth. Lambing: the mother licks the first lamb while giving birth to the second. Birth is the act or process of bearing or bringing forth offspring, [1] also referred to in technical contexts as parturition. In mammals, the process is initiated by hormones which cause the muscular walls of the uterus to contract, expelling the fetus at a ...
The good genes hypothesis states that the choosy sex will mate with individuals who possess traits that signify overall genetic quality. In doing so, they gain an evolutionary advantage for their offspring through indirect benefit. The Hamilton–Zuk hypothesis posits that sexual ornaments are indicators of parasite- and disease-resistance.
